What is your favorite 1 hit wonder from the 70's?


Many on Audiogon agree the 1970's was the best decade for popular music. Whether it was the quality of songwriting or the diversity of music. The decade also produced many unforgettable 1 hit wonders. My personal favorite is Afternoon Delight by Starland Vocal Band, what's yours?

Ozz, Inna Gadda Da Vidi was 60's. I saw Iron Butterfly when the song was a hit.
Stuck in the Middle with You was really Gerry Rafferty, he had a string of hits.

What was the hit by 'Spiral Starecase'?
(Pretty sure that was 70's but maybe it was 60's also).
Not necessarily my one and only one and only but certainlyh worth recalling, Blues Image's "Ride Captain Ride". Don't think I saw that posted previously.
I believe that Spiral Staircase charted with "More Today Than Yesterday". Great song, but late '60's IIRC.
